摘要:
A complex apparatus (image processing apparatus) requests the transmission of an identification number from a security box (data processing apparatus). The security box transmits the stored own identification number to the complex apparatus. When no response is received within a predetermined time after the request of transmission of the identification number, or alternatively when the identification number transmitted from the security box differs from the identification number of a security box stored in advance, the complex apparatus displays a warning screen indicating that the appropriate security box has been removed, on the displaying section of the operation panel, and then turns ON a notifying lamp.

A digital multifunctional device 1 comprises an image reading unit 2, a hard disk 12, an image forming unit 6 and a device control unit 8. When there is input of a new image data through the image reading unit 2 while the device control unit 8 is invalidating a preceding image data stored in the hard disk 12, the invalidation by the device control unit 8 of the preceding image data in the hard disk 12 is interrupted, and the new image data being input is utilized to invalidate the preceding image data.

In a printer 1 which is an information processing apparatus of the present invention, after a password is accepted from a PC 2 together with image data and job information, the image data is encrypted and stored in a storage part 106, the job information is associated with the password and stored in a management part 104 as a job management table, and the process waits. In a case where a security program is executing, in case that a main power 110 is turned off, the operation of a backup part 105 to supply power to the management part 104 is inhibited, so that the job information table stored in the management part 104 is deleted. In a case where the security program is not executing, power is supplied to the management part 104 by the backup part, thereby maintaining the job management table stored in the management part 104.
摘要:
A disk recording checking method in which recording is performed on a disk having radially different recording tracks each divided circumferentially into a plurality of sectors. The method employs a continuous writing device for continuously writing data onto a predetermined number of the sectors, and a continuous checking device for checking the data, while continuously reading the data from the predetermined number of the sectors. The method utilized checks both the number of errors in each code sequence and the total number of errors in each sector to determine if the data in the sector is valid.
摘要:
A disk recording method in which recording is performed on a disklike recording medium having a radially coaxial or spiral recording track that is divided into a predetermined plural number of recording sectors each acting as a recording unit. A predetermined number of dedicated sectors are provided at a rear portion of the recording track so that the contents that are recorded in defective sectors of the recording sectors are alternatively assigned to the dedicated sectors.
摘要:
Intake and exhaust ports of an internal combustion engine possess respective turbine impellers, and an electrical rotary machine is formed on a rotary shaft connecting the impellers. Sensors are provided for sensing the loaded state of the engine at all times based on engine rpm and the amount of fuel supplied to the engine. When the engine is overloaded, the electrical rotary machine is made to operate as a motor to assist in the supercharging of the engine. When the engine load is not excessive, the rotary machine is made to operate as a generator to charge surplus energy, derived from the engine exhaust, in a storage battery.
摘要:
An image processing device comprises an image data input means 2, an image data storage means 12 for storing the image data being input, an image data processing means 6 having multiple processing modes for outputting the stored image data, and a image data erasing means for erasing the image data stored in the storage means 12. The device further comprises erase count control means 8, 14 for controlling the number of times for erasing image data capable of having the number of times of erase set arbitrarily according to the security level required for each mode, and capable of having the set number of times of erase changed in mid-flow. Confidentiality is protected by performing erase operations repeatedly to the region storing the unnecessary image data according to the security level.
